Evening.

Nice to see people read the terms and conditions when signing up, isn't it?

Takes about a month to get 1BTC at ~600MH/s.  With your 3MH/s it'd take 16 years.  16 years of mining to make £50.   

As I was saying....

I'm using GUIMiner.  

Forget about it, you're just wasting your time and electricity.

I've never used anything other than stratum, and I can see my rewards going up every few minutes.

Then again, I'm not wasting my time CPU mining. 

Pretty much, yeah.

Just under 600MH/s across two machines.  One is running a HD7770 and a HD6450.  The other a HD6970.

ATI is where it's at for mining.  Even my ancient HD6450 is pulling 22MH/s.  Pretty good for a generic old passive cooled card.  Sits in the bottom slot chugging away beneath my HD7770.

The HD6970 is a bit of a beast, got it running in my dedicated miner machine, got that card for £100 used.  Paid for itself in a month thanks to the price bubble a few weeks ago.
